I'm reminded of how one comic book writer (can't remember who) described Hal Jordan as the anti-Batman: While Batman prepares six ways to Sunday for everything, GL never prepares for anything. He has the skills and the wits to improvise a solution on the spot no matter what trouble rears its head, and he knows it. The writer said that part of the appeal of classic Hal Jordan is how his whole set-up -- the test pilot job, the 24-hour power limit, the vulnerability to yellow -- played into this. It's the whole "Oh no, that robot's yellow, so what do I do? Hmmm. Well, what about... this!" thing.
To someone like that, Batman probably comes off like the one guy you know who puts pictures of all his receipts online in case they ever burn in a fire or something and, worse, gets on everyone else's case for not doing the same.
